IMPROVEMENT IN MACHINES FOR COVERING THE HEADS 0F BOTTLES WITH TIN-FOIL CAPS.

Specification forming part of Letters Patent No. l 52,325, dated June 523, 1874; application filed January 10, 1874.

To all whom 'it may concern:

Be it known that we, REINEoLnBoEKLEN, of the city of Brooklyn, in the t ointy of Kings and State of New York, and FRIEDEEICH PFAENDER, of the city, county7 and State of New York, have invented certain Improvements in Machines for Covering the Heads'of Bottles with Tin-Foil Caps, of which the following is a specication:

This invention relates, rst, to the arrangement of spring-roller pressers, which serve to spin and lay the tin-foil cap over the head of the bottle, and which are provided with mechanism for adjusting them together in a ready manner to the dimension of any otl the usual heads of bottles desired to be covered, and so as to revolve eoncentrically around, and without vibrating inconveniently, the bottle. By these means the machine is readily adjustable for all ordinary variations of bottles without patterns for them, and the pressers yield properly to the inequalities ofthe head ofthe bottle, and the bottle can be easily held steady during the operation of covering its head. The invention relates, secondly, to the arrangement of said pressers relative to the motion and position of the head of the bottle, and provid ing said pressers with fulcrums, so that said pressers close and tightly lay the tin-foil cap over the head of the bottle while entering, and that the pressers a-re caused to open and release the tin-foil cap in withdrawing the bottle. By these means the pressers of the machine are not lia-ble to loosen the tin-foil cap in withdrawing the bottle from them, and a comparatively less thick and less expensive tin-foil can be used than by the use of the ordinary machine.

In the annexed drawings, Figure l represents a vertical central longitudinal section of the machine with our improvements. Fig. 2 is a face view of the same.

A represents the spindle-head or bearings and bed of the machine. B is the spindle, which works freely in the bearings,and has a pulley, O, secured upon it, by which it is rotated. rlhe spindle B is hollow, as shown, a-nd has in its central opening a sliding rod, D.

spring, K, employed upon the forward part ot' the rod D ,between the collar H anda shoulder, L, in the central opening of the spindle, the rod D is pressed forward, and to stop it from passing forward more than desired, we employ a screw-nut, M, upon the rear end of said rod. N N N represent the pressers of the machine.

They are provided with rollers O O O in theirworkin g ends to prevent them from cutting the tin-foil in passing over it. Each presser has a rod, I), or tail end, which passes through a cross-piece, Q, and the cross-piece has trunnions R E to allow it to turn in a dog, S, in which it is mounted. Each dog S is properly itted to slide in one of the radial slots G of the faceplate F. By means of a rear plate, T, which has spiral slots U U U and a set-screw, V, on each dog, passing through one of the slots U, the dogs are moved together, and are readily adjusted from and to the center of the spindle B, and the pressers, being attached to the dogs, are consequently readily adj usted to the dimension of the head of the bottle operated upon. rlhe rear plate T is fitted to turn freely upon the head E, and the head E has a circular screw-nut, WV, for tightening said rear plate against the face-plate F after the dogs S have been adjusted. The fore parts of the dogs 'are properly slotted to guide the cross-pieces Q, as well as the forked ends of the pressers, which are provided with the rollers O, for which purpose the said ends are shaped with an enlargement, as shown. Each presser is provided with a small spiral spring, X X, upon its rods, between its forked end and the cross-piece Q, to allow the presser to yield to the irregularities ot' the bottle-head; and the ends of the rods P have screw-threads and nuts to hold the pressers in their places and nnd enuse the tin-foil to lie tightly upon and @over the head of the bottle until closing upon the neel; ofthe bottle. The bottle is thereafter withdiuwn, by which motion the pressers have lyielded outwardly and allowed the head of the bottle to Withdraw Without loosening or discurbing` the tiirfoil enp.

/Vhat We claim as our invention, and desire to secure by Letters Patent, is-

l. The adjustable dogs S and pressers N, in combination with the spindle B, rod D, faceplate F, and rear plate T, substantially as and for the purpose herein set forth.

2. The pressers N, arranged-t0 yield out- Wardly, in combination with the dogs S, substantially as and for the purpose shown and described.
